Most of us are probably feeling like we drank our bodyweight in alcohol and had one too many mince pies this Christmas.

But judging by Charlotte Crosby’s latest Instagram snap, she looks like she's been a proper good lass this festive period.

Posting a picture of her former self, alongside a slimmed down sexy snap wearing a black playsuit and matching stockings, with the caption: 'Looking back at photos when I was bigger takes me back to a BAD place!
'But then when I have ones like the one on the right to compare it to! I just feel massively proud at how far I've came! (sic).'

But it's not just Charlotte's amazing body transformation that we're struggling to get our heads around, because the weight-loss worldie has also vowed to put her mortal antics on holdfor January. *SHOCK*

And it looks as though she won't be alone, because her all time BFF and former cock capturer queen, Holly Hagan, appears to be doing the same.

Posting on her Instagram holding a drink that we can only assume is a virgin Diet Coke, she wrote: 'Dry January'.

And yes, you read that correctly, Holly and virgin in the same sentence!

Stay stronglasses...
